CROSS-REFERENCE TO RELATED APPLICATION

This application is related to U.S. patent application Ser. No.14/339,383 titled “Selecting Best-Fit Digital Lockers for Packages,” andfiled Jul. 23, 2014, the entire contents of which are herebyincorporated by reference as if fully set forth herein.

FIELD OF THE DISCLOSURE

The present disclosure relates to a digital locker delivery system, andmore specifically, to configuring a digital locker delivery system tomanage a delivery of a package to a digital locker and to manage aretrieval of the package from the digital locker.

BACKGROUND

The approaches described in this section are approaches that could bepursued, but not necessarily approaches that have been previouslyconceived or pursued. Therefore, unless otherwise indicated, it shouldnot be assumed that any of the approaches described in this sectionqualify as prior art merely by virtue of their inclusion in thissection.

Digital lockers may be implemented as physical lockers equipped withcircuitries configured to manage access to the lockers. Some digitallockers may be managed locally; other digital lockers may be managedcentrally by a locker manager configured to communicate with thelockers.

Digital lockers may serve a vast range of industries, includingairports, train stations, sports facilities, schools, universities,factories, businesses and the like. For example, a section of industriallockers may be configured as a permanent fixture in a school, an office,a gym or a factory.

Digital lockers may be manufactured to suit a variety of needs, and maybe available in a wide range of shapes and sizes. The locker may beavailable as single compartment lockers, multi-compartment lockers, andthe like.

Some digital lockers are equipped with light sensors that are used todetermine whether any objects are present inside the lockers.Unfortunately, the readings from the light sensors may be inaccurate.For example, in situations when a light sensor is obscured by dust ordirt, the reading from the sensor may indicate that some object ispresent in the locker even if the locker is empty.

SUMMARY

Techniques are provided for determining, by a locker sensor, a weight ofan item placed in a locker compartment. The data indicating the weightof the item placed in the locker compartment is transmitted to a lockercontroller. In response to receiving, from the locker sensor, the dataindicating the weight of the item placed in the locker compartment, thelocker controller transmits the data to a locker manager. In response toreceiving, from the locker controller, the data indicating the weight ofthe item placed in the locker compartment, the locker manager requestsand obtains a reference weight for the item, and uses the obtainedreference weight to verify the weight of the item placed in the lockercompartment. Then, the locker manager generates and transmits the reportindicating whether the item has been delivered to the lockercompartment.

1.0 Overview

An approach is provided for managing a delivery of a package to adigital locker and for managing a retrieval of the package from thedigital locker. In an embodiment, managing of a package delivery andpackage retrieval is performed by various components of a digital lockersystem. The components of the digital locker system may cooperate witheach other, with other devices and computers, and with users.

In an embodiment, a digital locker system utilizes a variety of tools,including tools for measuring and weighing the packages. The tools mayinclude weight sensors, light sensors, infra-red sensors, opticalsensors, magnetic sensors, and the like. The sensors may be used todetermine various characteristics of a package, such as physicaldimensions of a package, a weight of the package, a color of thewrapping of the package, an appearance of the package, and the like.

Measuring and weighing tools may collect characteristics of a package,and the characteristics may be used to determine whether the package wasdeposited in a digital locker, whether a correct package was depositedin the locker, whether the package was retrieved from the locker, andthe like, or any combination thereof.

Measuring and weighing tools may be implemented in both apackage-handler and a digital locker. For example, one measurementsystem may be implemented in an entity handling a delivery of thepackage, and another measurement system may be implemented in a digitallocker to which the package may be delivered. The measurement system ofthe entity handling the delivery of the package may be configured todetermine a weight of the package before the package is dispatched to acarrier. The measurement system of the digital locker may be configuredto determine a weight of an item that has been delivered to a lockercompartment of the digital locker. As used herein, the term “lockercompartment” refers to a physical space associated with a digitallocker. A digital locker may include a single locker compartment ormultiple locker compartments, depending upon a particularimplementation.

In an embodiment, various readings of the weight of the package may becompared to determine whether the package was deposited in a lockercompartment. For example, the weight of the package determined by ameasurement system associated with the entity handling the delivery ofthe package may be compared with the weight of the package determined bythe measurement system associated with the digital locker. If theweights match within a certain error margin, then the digital locker maydetermine that the item present in the locker compartment is indeed thesame package.

Various readings provided by a digital locker may also be used todetermine whether a package was deposited in a locker compartment,and/or whether a package was retrieved from a locker compartment. Forexample, if the weight-readings change from about zero to the weightabove a certain weight threshold, then the digital locker may determinethat an item has been deposited in the locker compartment. However, ifthe weight-readings change from the weight above a certain weightthreshold to zero (within a certain threshold), then the digital lockermay determine that the item has been removed (or retrieved) from thelocker compartment.

Weight readings may also be used to determine a time period during whicha package remains in a locker compartment and/or to determine whetherthe package remains in a locker compartment longer than it is expected.For example, if a weight of an item deposited in a locker compartmentremains above a certain weight threshold for several days, and does notchange within the several days by more than 10% of the initial weight ofthe package, then a digital locker delivery system may generate amessage indicating that the package has not been timely retrieved fromthe compartment. The message may be used to urge a recipient of thepackage to retrieve the package from the locker.

However, if a package remains in a locker compartment less than acertain time period, then a sender and/or a recipient of the package maybe awarded for using the compartment for a short period of time, andthus increasing the usage-efficiency of the digital locker deliverysystem.

Weight readings may also be used to identify a locker compartments thatis empty and available for use. For example, if a weight of the contentsof the locker compartment remains below a certain weight threshold, thena digital locker delivery system may generate a message indicating thatthe locker compartment is empty, and thus available to customers.

In an embodiment, a digital locker delivery system identifies thebest-fit locker compartment for a package. The determination may bebased on a variety of factors, including the size of the package, thepopularity of the locker compartments, the demand of the lockercompartments, the availability of the locker compartments, and the like.For example, upon receiving a request to store a particular package, adigital locker delivery system may obtain the measurements of thepackage.

Measurements of a package may be obtained using a variety of measuringtools, such as optical sensors, electromagnetic sensors, mechanicalsensors, and the like. The measurements may include dimensionalmeasurement, such as height, width, and depth of the package, the weightof the package, or any other measurements that allow determining thesize and/or characteristics of the package.

The digital locker delivery system may also obtain measurements of thelockers that are empty and available. The measurements may be providedto the digital locker delivery system by digital lockers, by amaintenance service of the digital lockers, or otherwise.

Based on the measurements of the package and the measurements of thelocker compartments that are empty at the moment, a digital lockerdelivery system may determine whether any of the available lockercompartments is large enough to hold the package. If more than onelocker compartments are identified as large enough to hold the package,then the digital locker delivery system may select a particular lockercompartment that is large enough to hold the package, but that is alsothe smallest from all the locker compartments that could hold thepackage. This approach is referred herein as finding the best-fit-lockerfor the package.

Throughout this description, the terms a sender and a seller are usedinterchangeably. The terms a recipient and a buyer are also usedinterchangeably.

2.0 System Architecture

2.1 Single-Facility Digital Lockers

FIG. 1 is a block diagram that depicts example architecture of a digitallocker delivery system 10. Throughout the disclosure, digital lockerdelivery system 10 may also be referred to as a delivery system 10. Bothnames are used interchangeably herein.

In the depicted example, delivery system 10 comprises a digital lockerfacility 110, which may be implemented in a commercial building at anairport, a train station, a factory, or any other enterprise.

Digital locker delivery system 10 may be configured allow lockers in adigital locker facility 110 to communicate, via one or more computernetworks 155, with one or more sellers 172, 174, and one or more buyers182, 184. In an embodiment, delivery system 10 also includes a lockermanager 192, which uses one or more databases 194, and whichcommunicates with digital locker facility 110. Locker manager 192 and/ordatabases 194 may be used to manage digital lockers of digital lockerfacility 110. In some implementations, locker manager 192 and/ordatabases 194 are optional.

Digital locker facility 110 may include various digital lockers andfacilitate communications between the lockers, sellers 172, 174 andbuyers 182, 184. For example, digital locker facility 110 may include asystem of digital lockers and make the digital lockers available tosellers 172, 174 and buyers 182, 184.

In an embodiment, digital locker facility 110 comprises one or moredigital lockers 122, 132, 142, each of which communicates with its ownlocker sensors and locker controllers. For example, a digital locker 122may communicate with a locker sensor (LS) 124 and a locker controller(LC) 126; a digital locker 132 may communicate with a locker sensor 134and a locker controller 136; and a digital locker 142 may communicatewith a locker sensor 144 and a locker controller 146. A one-to-onerelationship between locker controllers and digital lockers is notrequired and a single locker controller may control more than onedigital locker, depending upon a particular implementation.

In an embodiment, locker sensor 124 and locker controller 126 are partof a locker compartment. Similarly, locker sensor 134 and lockercontroller 136 are part of a locker compartment. Also, locker sensor 144and locker controller 146 are part of a locker compartment. Otherorganization of locker compartments and digital lockers may also beimplemented.

Digital locker 122 (132, 142) may be a programmable unit equipped withCPUs, memory units, other components and computer software, and may beconfigured to monitor and control access to a locker compartment of thedigital locker.

Locker sensor 124 (134, 144) may be a programmable unit implementing oneor more optical sensors, magnetics sensors, weight sensor, and the like.Locker sensor 124 (134, 144) may be configured to determine a size, aweight, an appearance and other characteristics of an item deposited ina locker compartment.

Locker controller 126 (136, 146) may be a programmable unit configuredto control access to a locker compartment, transmit sensor informationfrom locker sensor 124 (134, 144) to other components of digital locker122 (132, 142), receive instructions from other units, and perform otheroperations.

In an embodiment, digital lockers 122, 132, 142 communicate with otherdigital lockers. For example, digital locker 132 may communicate notonly with its own locker sensor 134 and locker controller 136, but alsowith locker controller 126, which is a part of digital locker 122.Similarly, digital locker 142 may communicate not only with its ownlocker sensor 144 and locker controller 146, but also with lockercontroller 136, which is a part of digital locker 132. Othercommunications connections, not necessarily depicted in FIG. 1, may alsobe implemented.

In an embodiment, digital locker delivery system 10 comprises a lockermanager 152. In situations when each of digital lockers 122, 132, 142manage themselves and cooperate with each other, locker manager 152 maybe optional. However, if digital lockers 122, 132, 142 are notconfigured to manage the delivery of packages, locker manager 152 may beused to centrally manage the digital lockers.

Locker manager 152 may be configured to manage digital lockers 122, 132,142 and communicate instructions and messages between digital lockers122, 132, 142, and sellers 172, 174, and buyers 182, 184. For example,locker manager 152 may be configured to determine whether any lockercompartments, associated with digital lockers 122, 132, 142, are empty.Locker manager 152 may also be configured to determine which lockercompartment, associated with digital lockers 122, 132, 142, is the mostsuitable to hold a particular package.

Locker manager 152 may communicate with network 155 via an interface162. Interface 162 may be implemented as any data input/outputinterface. For example, interface 162 may be implemented as a graphicaluser interface, or any other type of the programmable interfaceconfigured to handle input/output transactions.

Network 155 may be any type of a communications network configured tofacilitate communications between users, devices and systems. Network155 may be a local area network, a wide area network, or a combinationof both.

Sellers 172, 174 represent user computers that individuals, such asmerchants, sellers or senders, may use to communicate with buyers 182,184, and digital locker facility 110. For example, sellers' computers172, 174 may be used to process purchase transactions, lease or rent adigital locker, request storing a package in a digital locker, monitordelivery of a package to a locker compartment, monitor retrieving of apackage from a locker compartment, and the like.

This may be illustrated using the following example: suppose that aseller who sells CD albums online uses seller computer 172 to advertisethe CD albums to potential buyers 182, 184. Upon receiving a purchaseorder for a particular CD album, the seller may use seller computer 172to process a purchase transaction, make arrangements for a packagecontaining the CD album to be delivered to a particular lockercompartment in digital locker facility 110, and monitor the lockercompartment to determine whether the package containing the CD album waspicked up by a buyer.

Buyers 182, 184 represent user computers that individuals, such asbuyers or recipients, may use to communicate with sellers 172, 174, anddigital locker facility 110. For example, buyers' computers 182, 184 maybe used to view websites and shopping networks, initiate purchasetransactions from the websites, monitor a delivery of purchased items,receive messages indicating whether the purchased items have beendeposited in a locker compartments, and the like.

This may be illustrated using the following example: suppose that abuyer used a browser launched on buyer's computer 182 to purchase onlinea pair of tickets to a concert. Once the purchase transaction iscompleted, the buyer may receive a purchase-confirmation message. Themessage may include a physical address of the digital locker facility110 and an access code for a particular digital locker compartment, inwhich the pair of tickets will be delivered to be picked up. Later on,once the buyer receives a message that the pair of tickets has beendeposited in a locker compartment of the digital locker having theparticular access code for the locker, the buyer may go to the digitallocker facility 110 and retrieve the pair of tickets from thecompartment.

Storage 194 may be any combination of volatile or non-volatile storageconfigured to store data 02. For example, storage 194 may be randomaccess memory (RAM), one or more disks, or any combination of RAM andone or more disks for storing scanned document data. Storage 194 may beused to store information about digital lockers, communicationsexchanged between the digital lockers, sellers, buyers and a lockermanager. For example, storage 194 may be used to store information aboutthe locker compartments that are empty, the locker compartments that areused to store items, the requests for locker compartments, and the like.

2.2. Multiple-Facility Digital Lockers

FIG. 2 is a block diagram that depicts example architecture of a digitallocker delivery system 12. In an embodiment, digital locker deliverysystem 12 comprises one or more digital locker facilities 110, 112, 113,that communicate via a network 155 with a locker manager 192, sellers172, 174 and buyers 182, 184. Each of digital locker facilities 110,112, 113 may correspond to a digital locker facility 110, described inFIG. 1. Network 155, sellers 172, 174, and buyers 182, 184 were alsodescribed in FIG. 1.

In an embodiment, digital lockers configured in digital lockerfacilities 110, 112, 113 communicate with each other and with a lockermanager 192. For example, digital lockers of digital locker facilities110, 112, 113 may exchange information about availability of lockercompartments, use-ability of the lockers, requests for the lockers, andvarious types of messages and notifications. Further, the digitallockers may receive requests and instructions from locker manager 192.

Locker manager 192 may be configured to centrally manage digital lockerconfigured in digital locker facilities 119, 112, 113. For example,locker manager 192 may query the digital lockers for the availabilityinformation of the locker compartments, and use that information toselect a particular locker compartment in one of digital lockerfacilities 110, 112, 113 that is the most suitable for storing aparticular package. This may be illustrated using the following example:suppose a seller requests a digital locker for storing a particularpackage. The request may include specification of the size and/or weightof the package. Alternatively, the size and/or weight of the package maybe determined by locker manager 192. The request for a digital lockermay be sent to locker manager 192. Upon receiving the request, lockermanager 192 may parse the request and extract from the request thesize-specification of the package. Alternatively, locker manager 192 mayquery the seller to provide the size-specification for the package, orobtain the size-specification from a third-party.

Upon receiving the size-specification of the package, locker manager 192may transmit the specification to digital locker facility 110 todetermine whether digital locker facility 110 has a locker compartmentthat is large enough to hold the package. In response, locker manager192 may receive one or more responses from the digital lockersimplemented in digital locker facility 110. If the digital lockersimplemented in digital locker facility 110 do not have a lockercompartment large enough to hold the package, then locker manager 192may query the next digital locker facility, such as digital lockerfacility 112, and so for. Alternatively, locker manager 192 may queryall the digital lockers in all available digital locker facilities 110,112, 113 simultaneously.

Upon receiving responses from the digital lockers, locker manager 192may determine whether a locker compartment that is large enough to holdthe package is available. If such a locker compartment is available,then locker manager 192 may collect the identification information ofthe locker compartment, and transmit the information to the seller.Although embodiments are depicted in the figures and described herein inthe context of using a single lock manager for purposes of explanation,embodiments are not limited to implementations with a single lockmanager and any number of lock managers may be used, depending upon aparticular implementation. For example, multiple lock managers may beused for redundancy and load balancing.

2.1 Digital Lockers

FIGS. 3-4 depict examples of digital lockers. In the example depicted inFIG. 3 locker compartments of all illustrated lockers have the samesize, while in the example depicted in FIG. 3 illustrates lockercompartments have different sizes.

2.3 Digital Lockers with Similar Compartments

FIG. 3 is a block diagram that depicts an example digital locker 30. Thedepicted example includes an interface portion 1010 and a plurality oflocker compartments located and mounted around the interface portion1010. Depending on implementation, digital locker 30 may include onlyone interface portion 1010 (as depicted in FIG. 3), or may include aplurality of interface portions 1010. Each interface portion 1010 mayinclude various displays, controls and data entry sub-interfaces.

In an embodiment, interface portion 1010 comprises one or more touchpanels 1020, one or more sensors 1030, 1040, and one or more controls1050, 1060.

Touch panel 1020 may be configured to receive data from a user, anddisplay information for the user. For example, touch panel 1020 may beconfigured to display a menu containing various options that a user maychoose to initiate entering data to digital locker 30. A menu mayinclude displays of various screens containing one or more options thatthe user may select by touching the option-label, displayed in touchpanel 1020. For example, upon touching touch panel 1020, a main menuhaving one or more options may be displayed in touch screen 1020; once auser selects (or touches) a particular option from the one or moreoptions displayed in touch screen 1020, another menu may be displayed intouch screen 1020.

Menu options displayed in touch panel 1020 may allow a user to enteridentification data of the user, identification data of a lockercompartment, access code for a locker compartment, and the like. Forexample, a user may enter his login information, such as his name or alogin name. Then, the user may enter his password. Upon receiving thelogin information and the password from the user, digital locker 30 mayattempt to authenticate the user to digital locker 30, and if thecredentials provided by the user are valid, the user may be prompted toenter an identifier of a locker compartment, which the user would liketo use. Upon receiving the identifier of the locker compartment, theuser may be prompted to enter an access code for the compartment. If theuser enters a valid access code, then the locker compartment associatedwith the entered identifier may be opened for the user.

Sensors 1030, 1040 may include optical sensors, scanners, cameras,infra-red sensors, finger-papillary-lines readers, eye-iris-code reader,Quick-Response (QR) code readers, bar-code readers, and the like. Thesensors may be configured to collect information from users, objectspositioned in front of the sensors, or objects placed inside lockercompartments.

A Quick Response (QR) code is a two dimensional code for representingdata in a graphical form. In a QR code, data is encoded to stringscontaining ones and zeroes, and the strings are represented graphicallyas rows and columns containing black and white pixels. For example, a QRcode may utilize a two-dimensional array of pixels, wherein each pixelcan have associated one of two Boolean values. For example, if aparticular pixel has associated the Boolean value of “1,” then the pixelis filled with a black rectangle. However, if a particular pixel hasassociated the Boolean value of “0,” then the pixel is filled with awhite rectangle. Using the coding, the rows and columns of thetwo-dimensional array are filled with black and white rectangles, andgroups of the pixels are interpreted as the encoded data. Othercombinations of associations between the Boolean values and colors ofthe rectangles may be used.

In other embodiments, encoded data may be in the form of a bar code, inwhich data are encoded to a string containing ones and zeroes, and thestrings are represented graphically as a row of black and white bars.The encoded data can also be represented by one or more symbols, one ormore alphanumeric characters, or any other form of coding.

Some of sensors 1030, 1040 may be installed inside locker compartments,and may be used to determine whether any object is present in a lockercompartment. For example, some of sensors 1030, 1040 may be opticalsensors, which detect the light intensity and the light color. Based onthe detected light values, optical sensors determine whether a lockercompartment is open, whether an object is placed in a lockercompartment, whether an object is removed from a locker compartment, andthe like.

Some of sensors 1030, 1040, installed inside locker compartments, may beused to determine a weight of an object placed in a locker compartment.For example, some of sensors 1030, 1040 may be implemented aselectronics or mechanical scales and provide readings of the itemsplaced in a locker compartment. If the scale is calibrated when a lockercompartment is empty, then the scale sensor can provide a new readingwhen an object (having some non-null-weight) is placed in the lockercompartment. Then, if the object is removed from the locker compartment,then the scale sensor can provide another reading indicating that theobject was removed from the compartment.

In an embodiment, some of sensors 1030, 1040 are used to collect datafrom a user and/or from items held by the user in front of the sensors.For example, if the collected data includes depictions of the user, thenthe collected data may be used to authenticate the user. If thecollected data was scanned from a badge of a user, then the collecteddata may be used to authenticate the user. However, if the collecteddata includes QR code information collected from a mailing slip or amailing label, then the collected data may be used to identify apackage, a letter or other item. If the collected data includes bar-codedata collected from a package slip or other type of printed code, thenthe collected data may be used to identify a locker in which the packageis to be deposited, or a locker from which the package is to beretrieved. For example, if a user entered an identifier of a lockercompartment 310 and a valid access code for locker compartment 310, thendigital locker 30 may initiate opening of locker compartment 310.

Sensors 1030, 1040 may also collect other types of information useful inidentifying a user, a package, a mailing document, and the like. Forexample, sensors 1030 may be used to monitor surroundings of digitallocker 30 using cameras and other visual data collecting devices.

Controls 1050, 1060 may be configured to allow a user to navigate menusdisplayed in touch panel 1020, select options displayed in touch panel102, enter data to digital locker, and the like. For example, one ofcontrols 1050, 1060 may be used to display a menu in touch panel 1020,while another control may be used to navigate within the displayed menu,select options from the displayed menu, and so forth.

Interface portion 1010 may also include other components, not depictedin FIG. 3. For example, interface portion 1010 may include variousdials, LED displays, cameras, face recognition interfaces, fingerpapillary-lines recognition devices, and the like. The dials may beelectronically or mechanically operated, and may be used to enterlocker-identifiers and locker access codes. Finger-papillary-linesrecognition devices may be used to authenticate a user based on theunique distribution of the papillary lines on the user's finger.

2.4 Digital Lockers with Different Compartments

FIG. 4 is a block diagram that depicts an example digital locker 32. Incontrast to the example digital locker depicted in FIG. 3, the lockerdepicted in FIG. 4 includes locker compartments that vary in sizes. Forexample, digital locker 32 may include small compartments 310, mediumsize compartments 314, 315, 318, 319, and large compartments 312, 316,317 and 320. Lockers 314, 315, 318, 319 are larger than lockercompartment 310, but smaller than locker compartments 312, 316, 317,320. Furthermore, locker compartments 312, 320 appear to be suitable forstoring items that are rather tall, or at least taller than itemssuitable for storing in locker compartments 310, 318, 310. Moreover,locker compartments 316, 317 appear to be suitable for storing itemsthat are rather wide, or at least wider than items suitable for storingin locker compartments 310, 312, 320, 314, 315, 318, 319.

One of the advantages of including locker compartments having varioussizes is the ability to utilize the lockers more efficiently than if thelocker compartments were the same size. For example, if all the lockercompartments in a particular digital locker are the same size, thenitems are stored in the locker compartments as long as they fit into thecompartment. Hence, some of the locker compartment space may be unused;especially if the items are small, such as letters or pamphlets. Some ofthe locker compartment space may also be unused if the items to bestored are too small to hold such items.

However, when digital locker 32 contains locker compartments ofdifferent sizes, then locker compartments may be selected for a packageusing the best-approach. Using the “best-fit” approach for determining alocker compartment suitable for storing an item may improve efficiencyin using the storage space.

In an embodiment, digital locker 32 includes an interface portion 1010and a plurality of locker compartments located and mounted around theinterface portion 1010. Depending on implementation, digital locker 32may include only one interface portion 1010 (as depicted in FIG. 4), ormay include a plurality of interface portions 1010 (not depicted in FIG.4). Each interface portion 1010 may include various displays, controlsand data entry sub-interfaces. Touch panel 1020, sensors 1030, 1040, andcontrols 1050, 1060 are described in FIG. 3. Although embodiments aredepicted in the figures and described herein in the context of square orrectangular-shaped digital lockers for purposes of explanation,embodiments are applicable to digital lockers of any shape, e.g.,polygon-shaped, round and/or curved digital lockers.

2.5 Digital Locker Delivery System

FIG. 5 is a flow diagram that depicts communications exchanged between abuyer 510, a seller 520 and an intermediary 530. In an embodiment, anintermediary 530 is a company that provides shipping and logisticsservices. Intermediary 530 may be a package delivery company, a documentdelivery company, a courier-delivery-service company, an internationalexpress mail delivery company, an air-mail delivery company, and thelike. Some examples of intermediary 530 may include United ParcelService (UPS), FedEx, DHL, and others.

In an embodiment, an intermediary 530 is an electronic commerce companyand/or online retailer operating online shopping networks or conductingbusiness over the Internet. Examples of such companies may includeAmazon.com, eBay.com, and others.

The depicted diagram illustrates an example scenario in which a buyer510 places an order for an item offered by a seller 520; seller 520cooperates with an intermediary 530 in delivering the ordered item to adigital locker; and buyer 510 retrieves the ordered item from thedigital locker.

In this scenario, it is assumed that seller 520 or intermediary 530 havealready determined the best-fit locker compartment for storing the item.For example, it is possible that seller 520 owns and/or uses aparticular locker compartment, and seller 520 has been using theparticular locker compartment for shipping all his packages.Alternatively, the system may find the best-fit locker for each packagethat seller 520 sends to his customers. One approach for finding thebest-fit locker is depicted in FIG. 7.

Referring again to FIG. 5, in step 512, buyer 510 places an order for anitem offered by seller 520. Upon receiving the order in step 522, seller520 proceeds to dispatching the order to intermediary 530.

Intermediary 530 may be any entity involved in the delivery of ordereditems. For example, intermediary 530 may be a carrier or a shippingcompany that employs carriers or package delivery contractors. In somecases, intermediary 530 may be UPS, FedEx, DHL, or otherpackage-delivery company.

Upon receiving the order in step 532, intermediary 530 may, in step 534,make arrangements for delivering the ordered goods to a digital locker.The digital locker may be already identified in the received order.Alternatively, intermediary 530 may select the digital locker using theinformation included in the received order. For example, intermediary530 may check whether seller 520 already owns or indicated the locker inthe order. Also, intermediary 530 may contact a digital locker deliverysystem to determine whether any locker compartments that is large enoughto hold the ordered item is available. Furthermore, intermediary 530 maysend a request to a carrier to make arrangements for a lockercompartment.

In an embodiment, intermediary 530 (or seller 520, or any other entity)determines a digital locker for storing the ordered items. For example,if seller 520 provides size-dimensions of the package to be delivered,intermediary 530 may determine the best-fit locker for the package. Thesize-dimensions may include a height, width and depth of the box inwhich the ordered items are packed, and may be obtained using variousoptical or electronic sensors. Upon receiving the size-dimensions of thepackage, intermediary 530 may retrieve from a locker manager a list ofavailable locker compartments and their sizes. Using the receivedsize-dimensions and the list, intermediary 530 may identify a lockercompartment that is just large enough to store the package. Such alocker compartment may be referred to as a best-fit digital locker.

Once the ordered item is delivered to a digital locker, intermediary530, in step 536, may notify seller 520 that the ordered item has beendeposited in the digital locker. For example, intermediary 530 may senda notification or any type of message to seller 520 to let the sellerknow that the package has been delivered to the digital locker. Thenotification or the message may be dispatched to seller 520 as an email,a post at a social network, a text message, a voice message, or anyother type of message.

In an embodiment, intermediary 530 notifies seller 520, as depictedusing line 537, notifies buyer 510, as depicted using line 538, or bothseller 520 and buyer 510.

In an embodiment, intermediary 530 may notify both seller 520 and buyer510. For example, intermediary 530 may send the notification to seller520, as depicted in line 537, and may send the notification to buyer510, as depicted in line 538. The content and manner of notificationmay, or may not, be identical. For example, the notification sent tobuyer 510 may include an access code to the digital locker, so thatbuyer 510 may open up the locker compartment and retrieve the ordereditem from the compartment; while the notification sent to seller 520 maynot include an access code to the digital locker and the notificationsto buyer 510 and seller 520 may be made using different methods.

In step 526, seller 520 receives a notification from intermediary 530.The notification may indicate that the items ordered by buyer 510 havebeen deposited in a particular compartment of a digital locker. Forexample, the notification may indicate a physical address of the digitallocker facility at which the digital locker is installed, theidentification of the compartment and an access code to open the lockercompartment.

Alternatively, the notification may include a hyperlink to a web-pagethat contains a physical address of the digital locker facility at whichthe digital locker is located, the identification of the lockercompartment and an access code to open the locker compartment.

In an embodiment, the notification indicates that the location of thepackage will be provided to seller 520 (or buyer 510) in a separatecorrespondence, or a package mailing slip. The slip may include encodedinformation of the address, an identifier of the digital locker, andaccess code of the locker compartment at which the package has beendeposited. The encoded information may be in the form of a QR code, abar code, or any other code that seller 520 may use.

In step 528, seller 520 notifies buyer 510 that the ordered items havebeen delivered to a digital locker For example, seller 520 may sent anotification to buyer 510 to indicate the location of the lockercompartment in which the ordered items have been deposited.

In step 514, buyer 510 receives a notification from either seller 520,or intermediary 530, or both. The notification may include the addressinformation of the digital locker in which the ordered items have beendeposited. The notification may also include the locker compartmentidentification and an access code for the locker compartment.

In step 516, buyer 510 proceeds to the facility that contains thedigital locker identified in the notification received in step 514.Then, buyer 510 uses the access code to access the identified digitallocker, and picks up the ordered items from the locker compartment.

Once the goods are removed from a locker compartment, a digital lockermay notify a digital locker delivery system that the goods have beenretrieved from the locker.

Determining whether the goods have been retrieved from a digital lockermay be performed using a variety of methods and implementing a varietyof sensors. For example, a digital locker may monitor sensors installedinside the locker compartment, and upon receiving an indication that theweight-readings detected by the sensors indicate an empty locker, thedigital locker may deduce that that the items have been retrieved fromthe compartment.

The weight-readings provided by sensors of a digital locker may be usedto monitor a digital locker. The monitoring may be performed by variousentities, including intermediary 530, seller 520, and buyer 510. Themonitoring may be performed for many purposes, including determiningwhether an item has been deposited in the locker, whether an item hasbeen retrieved from the locker, whether the locker is empty, whether anylocker compartment large enough to hold a particular item is available,and the like.

One of the benefits of monitoring a digital locker is an increase in theutilization of the locker compartments. For example, a digital lockerdelivery system may monitor the locker compartments to determine howlong packages remain in locker compartments. A delivery system maycollect information about a time duration during which a package remainsin a locker compartment. If the time duration exceeds a certain amount,then a delivery system may generate and disseminate reminders forpicking-up the package. The reminders may be sent to buyers and/or thesellers, and are intended to encourage for example, a buyer to pick uptheir packages from a locker compartments shortly after the package isdeposited in the compartment.

Disseminating the reminders allows a delivery system to increase theutilization of the compartments. In some situations, a seller and/or abuyer may be charged fees if they let a package remain in the lockercompartment longer than a specified time. In other situations, a buyermay be charged fees if the buyer fails to pick up a package from alocker compartment shortly after the package was deposited in a lockercompartment. For example, if a buyer fails to pick up a package from alocker compartment for more than five days, then the buyer may becharged a fee to compensate a seller for the delay in receiving apayment for the selling the package to the buyer.

Another benefit of monitoring the digital lockers is to reward those whohelp to increase the utilization of the locker compartments. Forexample, a seller may offer some incentives or discounts to buyers whopick up their packages from the locker compartments shortly after thepackages are delivered to the compartments. Similarly, a delivery systemmay offer some incentives or discounts to the sellers and buyers who usethe locker compartments for short periods of time. The incentives mayinclude monetary discounts, coupons, merchandise discounts, servicediscounts, and the like.

In an embodiment, if seller 520 owns a digital locker, then seller 520may monitor a locker compartment managed by the digital locker. Themonitoring of the locker compartment may include determining whether apackage was deposited in the locker compartment, determining whether apackage deposited in the compartment has been picked up, how long apackage remained in the compartment, whether a package remained in thecompartment longer than a specified time, whether a package been pickedup within a specified time, and the like. For example, if a package hasnot been picked up from a locker compartment for more than seven days,then seller 520 may generate a reminder about the package, and send thereminder to buyer 510 to encourage the buyer to retrieve the packagefrom the compartment.

A digital locker may be also be monitored by intermediary 530 todetermine whether a package deposited in a locker compartment has beenpicked up, how long a package remains in the compartment, has thepackage remained in the compartment longer than a specified time, hasthe package been picked up within a specified time, and the like. Forexample, if the package has remained in the compartment for more thanseven days, then an intermediary may generate a reminder, and send thereminder to a seller, a buyer, or a digital locker system. The digitallocker system may notify a shipping company and encourage the shippingcompany to urge the buyer to pick up the package from the lockercompartment.

3.0 Examples of Digital Lockers

Digital lockers may be implemented using various methods and using avariety of components. An example implementation of a digital locker isdepicted in FIG. 6.

FIG. 6 is a block diagram that depicts an example digital locker 60.Digital locker 60 comprises a digital locker manager 152, touch panel622, various code readers 624, 626, various controllers 628, and one ormore locker compartments 642, 652, 662, 672. A locker compartment 642(652, 662, 672) comprises a physical locker compartment, a locker sensor644 (654, 664, 674) and a locker controller 646 (656, 666, 676). Lockersensor 644 (654, 664, 674) may be any type of electronic sensor,mechanical sensor, optical sensor, camera, scanner, and the likeconfigured to collect information about items, locker compartments andusers. Locker sensors are described in detail in FIG. 1.

Touch panel 622 may be configured to input data provided by a user, anddisplay information for the user. For example, touch panel 622 may beconfigured to display a menu containing various options that a user maychoose to initiate entering data to digital locker 60. A menu mayinclude displays of various screens containing one or more options thatthe user may select by touching the option-label displayed in touchpanel 622. Touch panels are described in detail in FIG. 3-4.

Bar code reader 624 and QR code reader 626 may be configured as datainput devices for scanning encoded information. For example, bar codereader 624 may be configured to scan the code from a mailing slip,decode the data, and transmit the decoded data to digital locker manager152. QR code reader 626 may be configured to scan a QR code displayed ona packaging or an identification card, and transmit the encoded data todigital locker manager 152. Code readers are described in detail in FIG.4-5.

Controller 628 may be configured to control one or more controls 632,634. Controls 632, 634 may be configured to accept input from a user andcommunicate the input to controller 628, which in turn, may communicatethe input to digital locker manager 152. Controls and controller aredescribed in FIG. 3-4.

Digital locker manager 152 may comprise one or more CPU units 610, oneor more RAM units 612, one or more USB ports 613 a to connect one ormore flash memory units 613 b, one or more I/O controllers 614, one ormore communication units 615, and one or more locker interfaces 616.

In an embodiment, digital locker manager 152 includes some additionalcomponents not depicted in FIG. 6. For example, digital locker manager152 may include one or more storage devices for storing data, or mayinclude one or more databases implemented in the storage devices.

In an embodiment, digital locker manager 152 is configured to controloperations and communications exchanged with digital locker 60 andwithin digital locker 60. For example, digital locker manager 152 maycontrol the usage of locker compartments 642, 652, 662, 672, controllocker interface 616, and control touch panel 622 to allow a user tocommunicate with digital locker manager 152. For example, digital lockermanager 152 may control interactions between digital locker manager 152and users, such as carriers, deliverymen, receivers of the packages, andusers returning the received goods.

Digital locker manager 152 may also be configured to communicate withlocker controllers 646, 656, 666, and 676. For example, digital lockermanager 152 may collect information from locker controllers 646, 656,666, 676 indicating whether items have been deposited in lockercompartments, whether items have been retrieved from lockercompartments, how long the times remained in the locker compartments,and the like. Locker controllers 646, 656, 666, 676 may also provide todigital locker manager 152 the indications whether locker compartmentshave been open or whether the locker compartments have been closed.

In an embodiment, locker controller 646 (656, 666, 676) is configured torequest and obtain weight-readings from locker sensor 644 (654, 664,674).

Locker sensor 644 (654, 664, 674) may be configured to determine aweight of an item deposited in locker compartment 642 (652, 662, 672),and provide the weight reading to locker controller 646 (656, 666, 676).Based on the received weight reading, locker controller 646 (656, 666,676) may determine whether the item was retrieved from lockercompartment 642 (652, 662, 672), whether locker compartment 642 (652,662, 672) is empty, whether locker compartment 642 (652, 662, 672) isavailable for storing an item, and the like.

4.0 Identifying the Best-Fit Locker for a Package

One of the benefits of determining the best-fit locker for a package isto improve the utilization of lockers. For example, if a digital lockerfacility maintains small lockers, medium lockers, and large lockers,then selection of a locker for storing a package may be based on thebest-fit-approach for matching the package with a locker.

In this approach, if the package is a letter, and a small locker islarge enough to hold the letter, then a delivery system may search for asmall locker and use such a small locker as the best-fit locker for theletter. Hence, if at least one small locker is available, then thedelivery system may select the small locker for holding the letter evenif medium lockers and large lockers are available. Using this approach,other lockers, such as medium lockers and large lockers, may remainavailable to other customers who wish to send items larger than thosethat fit in the small lockers.

In an embodiment, a digital locker delivery system determines andidentifies a locker compartment that is the best-fit compartment forstoring a package. In some situations, a sender or apackage-delivery-intermediary may provide an identification of a lockercompartment in which the package is to be deposited. In such situations,the delivery system may check whether the identified locker is largeenough to hold the package. If the identified locker is indeed largeenough, then the delivery system may use the identified locker forstoring the package. However, if the identified locker is too small, orotherwise not suitable for storing the package, then the delivery systemmay try to find a more suitable locker compartment.

In determining the best-fit locker compartment for a package, a digitallocker delivery system may take into consideration a variety of factors,including a size of the package, popularity of the locker compartments,availability of the lockers, demand on the lockers, and the like. Forexample, upon receiving a request to store a particular package, adelivery system may obtain the measurements of the package, and then,based on the measurements of the package, determine a particular lockercompartment that size-wise is large enough to hold the package. Thedelivery system may obtain the measurements of the package from otherentities, such as sellers, senders, a package delivery-intermediary, andthe like. For example, the measurements may be provided by UPS or FedEx.Alternatively, the measurements of the package may be provided by aseller or a sender of the package.

In situations when a package is actually delivered to a station of adigital locker delivery system, the system may use its own tools tomeasure the size of the package. For example, the size of the packagemay be determined using various optical scanners, electronic sensors,and the like.

Once measurements of the package are provided to a digital lockerdelivery system, the delivery system may use the measurements to find alocker compartment that is suitable for holding the package. One exampleof the process for collecting and identifying the most suitable lockercompartment is described in FIG. 7.

FIG. 7 is a block diagram that depicts a process of identifying abest-fit locker compartment for a package. In an embodiment, the processof identifying the best-fit locker compartment is implemented in adelivery system. For example, the process may be implemented in adigital locker manager 1104 of the delivery system. However, in otherembodiments, the process may be implemented in other components of thedelivery system or in other elements configured to implement theprocess.

In step 7010, locker manager 1104 receives encoded information from aseller, a sender or other entity that wishes to send a package or aletter to a recipient. The encoded information may include informationabout the package to be sent and instructions for sending the package.For example, the encoded information may include a name and an addressof the sender, a name and an address of the recipient, instructions forsending the package to the recipient, and any additional informationuseful in arranging the shipment of the package to the recipient.

In an embodiment, encoded information also includes a package handlinginstructions. For example, the encoded information may includeinstructions indicating the date by which the package is to be deliveredto a digital locker, whether a sender of the package is to be notifiedthat the package has been delivered to the digital locker, whether abuyer of an item included in the package is to be notified that thepackage has been delivered to the digital locker, whether the senderand/or an intermediary are to be notified when the package is picked upby the buyer, and the like. Furthermore, the encoded information mayinclude instructions pertaining to notifications that the packageremains in the digital locker longer than a certain period of time, andpertaining to information about any awards that are available if thepackage is picked up from the digital locker shortly after the packagewas delivered to the digital locker. Other instructions, such asinstructions to a carrier of the package or indications whether thepackage has been insured may also be included in the encodedinformation.

In an embodiment, encoded information is represented as a bar code. Abar code may be scanned using a bar-code-scanner, such asbar-code-reader 624 in FIG. 6. The scanned bar code may be translatedfrom the encoded form to a readable form using a software applicationconfigured to decode the encoded data.

In an embodiment, encoded information is represented as a QR code. A QRcode maybe scanned using a QR-code-scanner, such as a QR-code-reader 626in FIG. 6. The scanned QR code may be translated from the encoded formto a readable form using a software application configured to decode theencoded data.

In step 7012, locker manager 1104 analyses the decoded data and extractsidentification data from the decoded data. For example, the deliverysystem may extract from the decoded data the name of the sender, thename of the recipient, and the instructions for handling the package.Furthermore, the delivery system may extract identification, a nameand/or an address of an intermediary who has been selected for arranginga delivery of the package to a digital locker. The intermediary may beany entity that is capable of managing the package delivery, such asUPS, FedEx, DHL, and the like. The intermediary may be selected by asender of the package.

In situations when the sender of the package has not selected anintermediary, a locker manager may select an intermediary for thesender. For example, the locker manager may determine the intermediaryfor the sender based on a history of previous transactions initiated bythe sender. The locker manager may also determine the intermediary forthe sender based on a pool of the intermediaries available at a givenlocation and at the given time. Other methods for selecting anintermediary may also be implemented.

In step 7014, locker manager 1104 sends the extracted data to anintermediary. For example, the delivery system may send to theintermediary the name of the sender of the package, the name of therecipient, the address of the recipient, the instructions for handlingthe delivery of the package, and other information related to deliveringthe package to the recipient.

Upon receiving the extracted data, an intermediary may generate packageinformation for the delivery of the package. For example, anintermediary may generate a package slip, and include in the slipinformation about the sender, the recipient, and handling the package.The information included in the package slip may be presented in anencoded form, such as a bar code, a QR code, or any other code that alocker manager may decode.

In an embodiment, an intermediary also determines a digital locker towhich the package is to be delivered. For example, an intermediary mayhave a list of digital lockers that are available and empty at themoment, and use the list of the digital lockers to determine aparticular digital locker that has a locker compartment large enough tohold the package. Various methods for determining such a digital lockerare described in FIG. 8.

Alternatively, an intermediary may receive identification informationabout the digital locker from a sender or from a buyer. For example,some sellers prefer to use certain digital lockers installed inparticular locations. For example, if a seller sends a package to abuyer located in San Jose, Calif., and the seller often uses the digitallockers installed in the downtown-train-station in San Jose, then theseller may notify the intermediary that the package is to be deliveredto a digital locker installed in San Jose′ train station. However, theseller may also delegate the task of selecting a digital locker for thepackage to the intermediary.

In step 7016, locker manager 1104 sends a request to an intermediary toprovide package information for the package. Upon receiving the request,the intermediary sends the package information to the delivery system.

In an embodiment, the package information identifies the sender, thebuyer, the package-handling instructions, and the like.

In an embodiment, the package information also includes identificationof a digital locker to which the package is to be delivered. The digitallocker might have been selected by a sender of the package, or otherwiseprovided to the intermediary. Including in the package information theidentification of the digital locker to which the package is to bedelivered is optional. Hence, while in some cases the packageinformation includes the digital locker's identification, in othercases, the package information does not provide the locker'sinformation.

In step 7018, locker manager 1104 analyses the received packageinformation and determines whether the package information includesidentification of the digital locker to which the package is to bedelivered. For example, the locker manager may parse the packageinformation and search of an identifier of a digital locker. Theidentifier may be provided in a form of a code that uniquely identifiesa digital locker facility and the digital locker in the digital lockerfacility.

If the locker manager determined that the package information containsthe identification of the digital locker, then the process proceeds tostep 7022. Otherwise, the process proceeds to step 7020, in which lockermanager 1104 tries to find the best-fit locker for the package.

In step 7020, locker manager 1104 searches for the best-fit locker forthe package. Searching for the best-fit locker may include determiningthe measurements of the package, determining measurements of available(empty) lockers, and finding the best match between the measurements ofthe package and the measurements of the lockers.

In an embodiment, locker manager 1104 requests and receives measurementsof the package from an intermediary, a seller, or a sender of thepackage. For example, locker manager 1104 may determine an identifier ofthe package from tracking information of the package, and requestproviding the measurements of the package identified by the identifier.

In an embodiment, locker manager 1104 requests and receives measurementsof the empty lockers from a database maintained by locker manager 1104.For example, locker manager 1104 may determine identifiers of the emptylockers, and retrieve the measurements of the empty lockers identifiedbased on the identifiers.

Once locker manager 1104 receives the measurements of the package andthe measurements of the empty lockers, locker manager 1104 may executean optimization-based-application, which may determine the locker thatis the best-fit locker for the package.

In step 7022, a locker manager 1104 verifies whether a lockercompartment of the digital locker identified in the package informationis large enough to hold the package. For example, in some cases theidentified digital locker may be too small to hold the package. In someother cases, the identified digital locker may too large to hold thepackage, and other more suitable lockers are available for storing thepackage. Hence, unless the particular digital locker was explicitlyrequested by a seller or other entity, the delivery system may verifywhether another digital locker that is more suitable for holding thepackage is available.

If the identified digital locker is the best-fit locker for the package,then the process proceeds to step 7030, in which locker manager 1104generates a notification indicating that the digital locker, identifiedby the locker identifier, is large enough to hold the package. However,if the identified digital locker is not large enough to hold thepackage, then the process proceeds to step 7024.

In step 7024, locker manager 1104 determines whether any empty locker isavailable at the moment. For example, locker manager 1104 may try todetermine one or more digital lockers that are empty at the moment.

If at least one empty locker is found, then the process proceeds to step7020, in which locker manager 1104 determines which of the empty lockersis the best-fit lockers for the package. Otherwise, the process proceedsto step 7026, in which locker manager 1104 sends a notification to aseller or a sender to inform them that no suitable locker is availablefor the package at the moment. That may happen when the digital lockeridentified by the sender or the seller is too small to hold the packageand no other suitable locker for the package is available at the moment.

5.0 Delivering a Package to a Digital Locker

5.1 Flow Chart

FIG. 8 is a flow chart that depicts a process of delivering a package toa digital locker. For the purpose of describing the process, it isassumed that a seller or a sender of a package has already delivered thepackage to an intermediary, or made arrangements for the package to bedelivered to the intermediary from some location. For example, a sellermight have delivered the package directly to the intermediary, or theseller might have made the arrangements for a warehouse or a courier todeliver the package to the intermediary.

In an embodiment, an intermediary 1102 is a company that providesshipping and logistics services. Intermediary 1102 may be a packagedelivery company, a document delivery company, acourier-delivery-service company, an international express mail deliverycompany, an air-mail delivery company, and the like. Some examples ofintermediary 1102 may include UPS, FedEx, DHL, and others. Intermediary1102 may also be Amazon.com eBay.com, and others.

In an embodiment, a locker manager 1104 corresponds to a digital lockermanager 152, described in FIG. 6, and may be implemented in softwareand/or hardware. Locker manager 1104 may be configured to manage one ormore digital lockers and communicate instructions and messages betweenthe digital lockers, sellers, and buyers. Locker manager 1104 may alsobe configured to determine which locker compartments associated with thedigital lockers are empty, and/or which locker compartment associatedwith the digital lockers is the most suitable to hold a particularpackage.

In an embodiment, a locker manager 1104 corresponds to a digital lockermanager 192, described in FIG. 2, and may be implemented in softwareand/or hardware. Locker manager 1104 may be configured to manage one ormore digital locker facilities. Locker manager 1104 may or may not bephysically located at the digital locker facilities that the lockermanager manages. For example, locker manager 1104 may be located at alocation separate from the digital lockers that the locker managermanages.

In step 802, intermediary 1102 receives a package that a seller or asender wishes to have delivered to a digital locker. The package mayinclude a printed label or a note indicating the sender, and therecipient of the package. For example, the package may have an attachedlabel indicating the name and the address of the sender, the name andthe address of the recipient, and other information, such aspackage-handling instructions, and the like.

In step 804, intermediary 1102 determines a weight and dimensions of thepackage. The weight and dimensions of the package may be determinedusing various scanners and sensors, including optical sensors,electronic sensors, mechanical sensors, and the like. The variousmethods for determining a weight and dimensions of the package aredescribed in FIG. 6.

In step 806, intermediary 1102 associates measurements of the weight anddimensions of the package with tracking data. For example, themeasurements may be entered into a database maintained by intermediary1102, and saved in a tracking data record.

Besides the measurements of the package, a tracking data record may alsoinclude the identification of the package, the name/address of thesender, the name/address of the recipient, and other information. Thetracking data record may have an assigned identifier or a sequencerecord. The identifier may be also referred to as a tracking number. Theidentifier (tracking number) may be used to uniquely identify and trackthe delivery of the package. For example, upon entering the trackingnumber into the system, a user may obtain a display of the informationabout the package and the real-time tracking information.

In step 808, tracking data for a package is saved in a database. Forexample, the tracking record for the package may be saved in a databasemaintained by intermediary 1102. The tracking data may also be printedout on a physical tracking label, and the tracking label may be affixedto the package.

In an embodiment, prior to printing the tracking label for a package,the tracking data is encoded into a bar code or a QR code. Once thetracking data is encoded, the encoded tracking data may be printed on aphysical tracking label, and then, the label may be affixed to thepackage.

In step 810, locker manager 1104 receives tracking data for a package.For example, a delivery person (a courier) may use a sensor or a scannerto scan an encoded tracking label affixed to the package, and thescanner may transmit the scanned encoded tracking information to lockermanager 1104. The delivery person may be a person hired by intermediary1102 to deliver the package to a digital locker.

In an embodiment, locker manager 1104 receives tracking data for apackage from a digital locker controller of a digital locker. Forexample, if the delivery person used a scanner to scan an encodedtracking label on the package, then the encoded data may be transmittedfrom the sensor/scanner to a digital controller, and the digitalcontroller may communicate the encoded data to locker manager 1104.

In step 812, locker manager 1104 decodes the encoded tracking data,parses the decoded data, and determines whether the parsed informationincludes an indication of a digital locker to which the package is to bedelivered. For example, the decoded data may include an identifier ofthe digital locker that a seller owns and wants to use for storing thepackage.

If the decoded data contains an indication of a digital locker to whichthe package is to be delivered, then the process proceeds to step 816.Otherwise, the process proceeds to step 814.

In step 814, locker manager 1104 tries to find the best-fit locker forthe package. To find the best-fit locker for the package, locker manager1104 may retrieve or otherwise obtain measurements of the package. Forexample, locker manager 1104 may parse the decoded tracking data todetermine whether the measurements of the package are included in thetracking information in the tracking label affixed on the package. Ifthe tracking information does not contain the measurement informationfor the package, then locker manager 1104 may request the measurementinformation from intermediary 1102.

According to another example, locker manager 1104 may also request themeasurements information from other sources, such as a seller or otherentity facilitating the handling of the package.

Furthermore, locker manager 1104 may display a message on a touch panelfor a package-delivery person. The message may provide instructions forplacing the package in front of one of the sensors of the digitallocker. Examples of the sensors include sensors 1030, 1040, described inFIG. 3-4. The sensor may scan a three-dimensional image of the package,and based on the scanned image, locker manager 1104 may determine thedimensions of the package. Other methods of determining the dimensionsof the package by locker manager 1104 may also be implemented.

Locker manager 1104 may also retrieve, or otherwise obtain, informationabout the available digital lockers. For example, locker manager 1104may retrieve information about locker compartment of the digital lockersthat are available (or empty) at the moment. The information about suchlocker compartment may include the dimensions of the lockercompartments. If such information is readily available to locker manager1104, then locker manager 1104 may simply retrieve such information fromits own database or data storage.

However, if such information is not readily available, then lockermanager 1104 may send a request to one or more digital lockers tocollect and provide such information. For example, locker manager 1104may ask that the digital controllers of the digital lockers collect theinformation from locker sensors, and provide the collected informationto locker manager 1104. Functionalities of the digital controllers andthe digital sensors are described in FIG. 6.

Once the measurements of the package and the dimensions of the availablelocker compartments are received, or otherwise obtained, by lockermanager 1104, locker manager 1104 may use them to determine the best-fitlocker for the package. For example, locker manager may compare themeasurements of the package with the dimensions of the available lockercompartments, and select the locker compartment that is large enough tohold the package. Various methods of determining the best-fit locker forthe package are described in FIG. 7.

Once the best-fit locker for the package is identified, locker manager1104 may allow opening the best-fit locker so that the package may bedeposited in the locker. This may be accomplished in a variety of ways.For example, locker manager 1104 may retrieve an access code for theidentified locker, and send the access code to a digital controller ofthe identified locker. Upon receiving the access code, the digitalcontroller may unlock the locker, and, in step 816, open the door of thelocker.

According to another example, locker manager 1104 may retrieve an accesscode for the identified locker, and send the access code to intermediary1108, which in turn, may communicate the access code to apackage-delivery person. Upon receiving the access code, thepackage-delivery person may enter the access code to the digital lockerusing a touch panel of the digital locker. Examples of the touch panelsare described in FIG. 3-4.

In step 818, locker manager 1104 detects that a package has been placedin a digital locker. Locker manager 1104 may detect that using a varietyof methods. For example, locker manager 1104 may send a request to adigital control of the digital locker to provide weight readings fromthe digital locker. The weight readings may be obtained and collected byone or more sensors installed in the digital locker.

Locker manager 1104 may use the weight readings received from a digitalcontroller to monitor the weight readings and determine whether thereadings indicate an increase in weight. The weight increase occurs whena package is delivered in the digital locker compartment, and because atthat moment, the sensors register an increase in the weight of thecompartment. The weight increase may be monitored periodically and usinga certain error margin.

When the weight readings provided by a digital controller indicate thatthe weight of the compartment has been increased, locker manager 1104may determine that a package has been deposited in the locker. In anembodiment, locker manager 1104 may compare the weight reading with areference weight of the package to determine whether the item deliveredto the locker is indeed the package.

In step 820, locker manager 1104 sends a message to a digital controllerof the digital locker to close the locker. The locker may be closedautomatically be the digital controller, or a message may be displayedon a touch panel of the digital locker with instructions for closing thelocker. For example, locker manager 1104 may send a message to thedigital controller to enable closing the locker compartment, and at thesame time, display a message on the touch panel for a package-deliveryperson to physically close the door of the digital locker.

In step 824, locker manager 1104 generates a delivery report indicatingthat the package has been successfully delivered to the digital locker.The delivery report may be sent to various individuals and entities. Forexample, the delivery report may be sent a sender of the message, and/orto a recipient of the package. The delivery report may also be sent tointermediary 1102, or any other packet-handling entity involved inshipping the package.

In step 826, intermediary 1102 receives a delivery report from lockermanager 1104. Upon receiving the report, intermediary 1102 may send amessage to a sender, or a seller, of the package. The message mayindicate that the package was successfully delivered to a digitallocker, and that the package is ready to be picked up by a recipient ofthe package.

In an embodiment, a message may also include instructions for using thedigital locker in which the package was deposited. For example, themessage may provide identification of the digital locker and an accesscode to open the locker. The identification may include a physicaladdress of the facility at which the digital locker is located, and thenumber (or an identifier) of the digital locker.

In an embodiment, a message may also specify that the sooner the packageis picked up from the digital locker, the larger award may be providedto a sender and/or to a recipient. For example, one type of message mayindicate that if the package is picked up within three days, then thesender and/or the recipient will be entered into a sweepstake or alottery and will have a chance to with some prizes. Another type ofmessage may indicate that if the package is not picked up within sevendays, then the cost of renting the digital locker by the sender will beincreased by a certain amount of money. Other type of message mayindicate that if the package is picked after more than thirty days, thenthe package will be removed from the digital locker by an associate froma digital locker delivery system. Other messages may also be sent to thesender and/or the recipient.

5.2 Time Chart

FIG. 9 is an example time chart for a process of delivering a package toa digital locker. In the depicted time chart, the communications areexchanged between a delivery person 710, a bar/QR code reader 712, alocker manager 713, an intermediary 714, a locker controller 715, alocker compartment 716, a locker sensor 717, and a seller 718.

The example depicted in FIG. 9 is one of many examples of thecommunications exchanged between entities and elements 710-718 as apackage is delivered to a digital locker. In other examples, thecommunications may be exchanged between some of the entities andelements 710-718, but not all of them. In yet other examples,communications other than those depicted in FIG. 9 may be exchangedbetween the entities and elements 710-718.

Referring to FIG. 9, in an embodiment, a delivery person 710 is inpossession of the package that a seller 718 wishes to have delivered toa package's recipient. Delivery person 710 may use a scanning device toscan, in step 920, a label affixed to the package. The label may includeinformation about the package, such as the tracking number of thepackage, the name/address of the sender of the package, the name/addressof the recipient, and the like.

In an embodiment, information included in the label affixed to thepackage is encoded into code. The code may be a bar code or a QR codeand may be generated and placed on the package by a seller or a packagecourier. The scanned code may be communicated to a bar/QR code reader712, which may decode the code, and store the decoded data.

In step 922, a bar/QR code reader may send the decoded data to a lockermanager 713.

In step 923, locker manager 713 may parse the decoded data, and extract,from the decoded data, information about the package. For example,locker manager 713 may extract, from the decoded data, the name/addressof the sender of the package, the name/address of the recipient of thepackage, instructions for handling the package, and other informationabout the package. Locker manager 713 may also extract, from the decodeddata, a tracking number of the package and other identificationinformation of the package.

While in some embodiments the above information may be included in thedecoded data, in other embodiments, the above information may be missingfrom the decoded data and a package-label. If the above information isnot included in the decoded data, then locker manager 713 may requestthat information from for example, an intermediary 714, a seller 718, orothers.

In step 924, locker manager 713 determines a destination of the package.For example, locker manager 713 may request the destination informationfor the package from intermediary 714. The request may include trackinginformation of the package, or other form of the identification of thepackage.

Upon receiving a request for providing destination information of thepackage, intermediary 714, may parse the request, and extract from therequest tracking information of the package. Using the trackinginformation of the package, intermediary 714 may retrieve thedestination information for the package. The destination information forthe package may include the address of the digital locker facility inwhich the package is to be stored.

In step 926, locker manager 713 receives destination information for thepackage. In an embodiment, the destination information for the packagemay include the address of the digital locker facility in which adigital locker for storing the package is present.

In step 928, locker manager 713 obtains a locker identifier of thedigital locker in which the package is to be deposited. For example, alocker identifier may be provided in tracking information included inthe label affixed to the package. According to another example, a lockeridentifier may be provided in the decoded data included in the label.According to yet other example, a locker identifier may be provided tolocker manager 713 by seller 718, intermediary 714, or other entity.

In step 930, locker manager 713 sends a request to a locker controller715 to open a digital locker that is associated with the lockeridentifier. Locker manager 713 may include in the request the lockeridentifier and a command indicating a request to open the digital lockeridentified by the provided locker identifier.

Upon receiving the request to open a digital locker associated with thedigital locker identifier, locker controller 715 causes a lockercompartment 716 to open the door of the locker. Locker controller 715may either mechanically release a latch or a clasp attached to the door,and cause the door open, or may send an electronic signal to thecircuitry of the locker compartment to open the door.

Once the door of the digital locker is open, in step 934, deliveryperson 710 places the package in the compartment of the digital locker.

In step 936, locker sensor 717 obtains a weight reading from the lockercompartment, and transmits the weight reading to locker controller 715.Because the weight of the locker compartment has been increased sincethe package was placed in the compartment, the weight reading obtainedby locker sensor 717 may be used to verify that one or more objects havebeen placed in the locker compartment.

In step 938, delivery person 710 closes the door of the lockercompartment, in which the package was deposited.

In step 940, locker sensor 717 detects that the door of the lockercompartment has been closed, and sends a signal to locker controller 715to indicate to locker controller 715 that the door of the lockercompartment has been closed.

In step 942, locker controller 715 receives a signal from locker sensor717. The signal may indicate that the door of the locker has beenclosed. In response to receiving the signal, locker controller 715causes a locker compartment 716 to lock the door of the locker. Lockercontroller 715 may either mechanically engage a latch attached to thedoor, and lock the door, or may send an electronic signal to thecircuitry of the locker compartment to lock the door.

In step 944, locker controller 715 generates a report message, and sendsthe report message to locker manager 713. The report message may includeinformation indicating that that the package was delivered and depositedin locker compartment 716. The report message may also includeidentification information of the digital locker that contains lockercompartment 716. Additional information may also be provided in thereport message. For example, the message may include identification ofthe package, identification of seller 718, identification of a recipientof the package, and the like.

In step 946, locker manager 713 receives the report message from lockercontroller 715, and uses the content of the report message to generate adelivery report. The delivery report may contain the same or some of theinformation as provided in the report message. The delivery report issent to intermediary 714.

In step 948, intermediary 714 receives the delivery report from lockermanager 713, and forwards the delivery message to seller 718. Thedelivery report may include information indicating that that the packagewas delivered and deposited in locker compartment 716, identificationinformation of the digital locker that contains locker compartment 716,identification of the package, identification of a recipient of thepackage, and the like.

Upon receiving the delivery report, seller 718 becomes aware of the factthat the package was successfully delivered to locker compartment 716,and that the package is ready for a pick-up. In response to receivingthe delivery report, seller 718 may send a message to a recipient to letthe recipient know that the package is ready for a pick-up at the lockercompartment 716.

6.0 Weight-Based-Verification of a Package Delivery

In an embodiment, a digital locker system is configured to measure andweigh content of a locker compartment of a digital locker. Themeasurements and weight may be determined using various weight sensors,light sensors, infra-red sensors, optical sensors, magnetic sensors, andthe like. The sensors may be used to determine various characteristicsof a package deposited in the locker compartment. The characteristicsmay include physical dimensions of a package, a weight of the package, acolor of the wrapping of the package, an appearance of the package, andthe like.

Measurement and weight characteristics may be used to determine whethera package was deposited in a digital locker, whether a correct packagewas deposited in the locker, whether the package was retrieved from thelocker, and the like.

Measuring and weighing tools may be implemented by both, an intermediaryand a digital locker. For example, one measurement system may beimplemented in an intermediary that handles delivery of the package tothe digital locker, and another measurement system may be implemented inthe digital locker. The measurement system implemented in theintermediary may be configured to determine a weight of the packagebefore the package is dispatched to a carrier. The measurement systemimplemented in the digital locker may be configured to determine aweight of an item deposited in a locker compartment.

In an embodiment, weight readings provided by a digital locker may betested whether they are greater than zero value. For example, if aweight reading provided by a digital locker is greater than zero (withinsome tolerance), then the digital locker may determine that one or moreobjects have been placed in a locker compartment of the digital locker.This test may be used to determine whether a package was deposited inthe locker.

In an embodiment, weight readings determined by a digital locker may becompared with weight readings determined by an intermediary. Forexample, if a non-zero weight reading determined by a digital lockercorresponds to a weight reading determined by an intermediary for thepackage, then the digital locker may conclude that an object depositedin the locker compartment appears to be indeed the package. Thiscomparison may be used to determine whether a particular package wasindeed deposited in the locker.

In an embodiment, weight readings determined by a digital locker may betested whether they approach zero value. For example, if weight readingsdetermined by a digital locker changed from non-zero values to zero(within some tolerance), then the digital locker may determine that oneor more objects have been removed from the locker compartment of thedigital locker. This test may be used to determine whether a package waspicked-up from the locker.

6.1 Flow Chart

FIG. 10 is a flow chart that depicts an example process of weight-basedverification of a package delivery. In the depicted example, lockersensor 1202 communicates with locker controller 1204, which in turn,communicates with locker manager 1104.

In step 1002, locker sensor 1202 determines a weight of the contentdeposited in a locker compartment of the digital locker. If the lockercompartment is empty, then the weight reading is most likely zero. Ifone or more objects are deposited in the locker compartment, then theweight reading is most likely greater than zero.

In step 1004, locker sensor 1202 transmits the weight reading to lockercontroller 1204. The weight reading may be encoded in a body of amessage that locker sensor 1202 may send to locker controller 1204.Alternatively, the weight reading may be encoded as a binary code, andthe binary code may be send to locker controller 1204 using any type ofa communications protocol.

In step 1012, locker controller 1204 receives the weight readingindicating the weight of the content of the locker compartment of thedigital locker. If no item is deposited in the locker compartment, thenthe weight reading is most likely zero. However, if one or more objectsare deposited in the locker, then the weight reading is most likelynon-zero.

Upon receiving the weight reading, locker controller 1204 may retrievean identifier of the digital locker, generate a data record containingthe identifier of the digital locker and the weight reading, and savethe data record in a database or a storage device communicativelycoupled to the digital locker. The data record may be searchable basedon the identifier of the digital locker, and may be searchable based onthe weight reading. For example, if the identifier of the digital lockeris provided, then the system may retrieve the data record containing theidentifier, and from the data record, the weight of the contentdeposited in the digital locker identified by the identifier may beretrieved. Similarly, if the weight reading is provided, then the systemmay retrieve one or more data records containing the weight reading, andfrom the data records, the one or more identifiers of the digitallockers that hold packages having the weight indicated by the weightreading may be retrieved.

In step 1022, locker manager 1104 receives the weight reading indicatingthe weight of the content of the locker compartment of the digitallocker.

In step 1024, locker manager 1104 tests whether the weight reading isclose to zero (within a certain tolerance). If so, then in step 1026,locker manager 1104 generates a message indicating that the lockercompartment of the digital locker is most likely empty. Thedetermination may be inaccurate because it is possible that a very smallpiece of paper, a note, or a small letter still remains in the lockercompartment even if locker sensor 1202 obtained the weight reading ofzero. However, as the sensor-technology becomes more and more advanced,the weight reading may become more accurate.

If the weight reading is not close to zero, then in step 1028, lockermanager 1104 retrieves a reference weight determined by an intermediary.For example, locker manager 1104 may provide an identifier of thedigital locker to the intermediary, and request that the intermediaryretrieve a data record containing the identifier of the digital locker.From the data record, locker manager 1104 may retrieve a referenceweight of the content of the package. The reference weight of thecontent of the package corresponds to the weight of the package beforethe package was dispatched to the digital locker.

In step 1030, locker manager 1104 verifies the weight reading obtainedfrom locker controller 1204 with the reference weight of the package. Ifthe weight reading obtained from locker controller 1204 matches thereference weight of the package, then locker manager 1104 may determinethat the package was indeed deposited in the locker compartment of thedigital locker. However, if the weight reading obtained from lockercontroller 1204 does not match the reference weight of the package, thenlocker manager 1104 may determine that something other than the packagewas deposited in the compartment.

In step 1032, locker manager 1104 generates a report message, and sendsthe message to a seller, a sender, an intermediary, or a recipient ofthe package. For example, if the weight reading obtained from lockercontroller 1204 matched (within a certain tolerance) the referenceweight of the package, then the report message may indicate to theseller, the sender and/or the recipient of the package that the packagewas indeed deposited in the locker compartment. The message may alsoinclude a timestamp indicating the date/time when the locker sensor 1202detected that the package was deposited in the compartment. The messagemay also include information about the digital locker, such as anidentifier of the digital locker, instructions for retrieving thepackage from the compartment, an access code for accessing thecompartment, and the like.

However, if the weight reading obtained from locker controller 1204 doesnot match (within a certain tolerance) the reference weight of thepackage, then the report message may indicate to a seller, a sender,and/or recipient that some problem occurred in delivering the package tothe digital locker, or that the package has still not been delivered tothe locker. The message may also include contact information to anintermediary and/or a delivery person responsible for delivering thepackage to the digital locker.

6.2 Time Chart

FIG. 11 is a time chart that depicts a process of weight-basedverification of a package delivery. In the depicted time chart, thecommunications are exchanged between a delivery person 710, a bar/QRcode reader 712, a locker manager 713, an intermediary 714, a lockercontroller 715, a locker compartment 716, a locker sensor 717, and aseller 718.

The example depicted in FIG. 9 is one of many examples of thecommunications exchanged between entities and elements 710-718 as apackage is delivered to a digital locker. In other examples, thecommunications may be exchanged between some of the entities andelements 710-718, but not all of them. In yet other examples,communications other than those depicted in FIG. 9 may be exchangedbetween the entities and elements 710-718.

Steps 920-948 in FIG. 11 correspond to steps 920-948 in FIG. 9, and havebeen described in detail in FIG. 9. Therefore, steps 920-948 are onlybriefly described in FIG. 11.

Steps 1155, 1166, 1177 and 1188 do not correspond to any steps describedin FIG. 11. Therefore, steps 1155, 1166, 1177 and 1188 are described indetail below.

In step 920, a delivery person 710, who is in possession of the packagethat a seller 718 wishes to have delivered to a package's recipient,scans a label affixed to the package. The label may include informationabout the package, such as the tracking number of the package, thename/address of the sender of the package, the name/address of therecipient, and the like. The information may be encoded into a bar codeor a QR code.

In step 922, a bar/QR code reader decodes the label information andsends the decoded data to a locker manager 713.

In step 923, locker manager 713 parses the decoded data, and extracts,from the decoded data, information about the package. Locker manager 713may determine for example, measurements of the package, a weight of thepackage and other characteristics of the package.

In step 1155, locker manager 713 finds a digital locker for the package.For example, locker manager 713 may request an identifier of the digitallocker for the package from intermediary 714. The request may includetracking information of the package, or other form of the identificationof the package.

In an embodiment, locker manager 713 finds the best-fit locker for thepackage. For example, locker manager 713 may request, or otherwiseobtain, the measurements of the package, and use the measurements tofind the best-fit locker for the package. The measurements may beprovided from Bar/QR code reader 712. Alternatively, locker manager 713may request the measurement data from intermediary 714 or from seller718. The process of finding the best-fit locker for the package isdescribed in FIG. 7.

Upon determining the best-fit locker for the package, locker manager 713may determine an identifier of the locker, and store the lockeridentifier in association with information about the package. Forexample, locker manager 713 may generate, or update, a tracking recordcontaining the locker identifier of the digital locker in which thepackage will be stored, and the tracking information of the package.

In step 930, locker manager 713 sends a request to a locker controller715 to open a digital locker that is associated with the lockeridentifier. Locker manager 713 may include in the request the lockeridentifier and a command indicating a request to open the digital lockeridentified by the provided locker identifier.

In step 932, locker controller 715 causes a locker compartment 716 toopen the door of the locker. Locker controller 715 may eithermechanically release a latch or a clasp attached to the door and causethe door open, or may send an electronic signal to the circuitry of thelocker compartment to open the door.

In step 934, delivery person 710 places the package in the compartmentof the digital locker.

In step 1166, a locker sensor 717 obtains a weight reading from thelocker compartment, and transmits the weight reading to lockercontroller 715. Because the weight of the locker compartment has beenincreased since the package was placed in the compartment, the weightreading obtained by locker sensor 717 may be used to verify that one ormore objects have been placed in the locker compartment.

In step 1177, locker controller 715 receives the weight reading fromlocker sensor 717, and reports the weight reading to locker manager 713.

In step 1188, locker manager 713 receives the weight reading from lockercontroller 715, and verifies whether the weight reading corresponds to areference weight of the package. The reference weight of the package maybe the weight determined by for example, intermediary 714 before thepackage was dispatched to delivery person 714. The reference weight ofthe package may also be determined by seller 718, a sender of thepackage, or other person who had an opportunity to weigh the actualpackage.

If the weight reading received from locker controller 715 matches thereference weight for the package within a certain tolerance, then lockermanager 715 may conclude that the package was indeed delivered to thedigital locker. However, if the weight reading received from lockercontroller 715 does not match the reference weight for the packagewithin a certain tolerance, then locker manager 715 may conclude thatthe package was not delivered to the digital locker. For example, if theweight reading received from locker controller 715 is zero, then lockermanager 715 may conclude that the digital locker is empty.

In an embodiment, upon verifying the received weight reading, lockercontroller 715 may generate a message and disseminate the message toseller 718, a sender of the message, or a recipient of the message. Themessage may indicate that for example, the package was indeed deliveredto the digital locker, that the digital locker is empty, or that someobject, other than the package, was deposited in the digital locker.

In step 938, delivery person 710 closes the door of the lockercompartment, in which the package was deposited.

In step 940, locker sensor 717 detects that the door of the lockercompartment has been closed, and sends a signal to locker controller 715to indicate to locker controller 715 that the door of the lockercompartment has been closed.

In step 942, locker controller 715 receives a signal from locker sensor717 indicating that the door of the locker has been closed, and locksthe door of the locker.

In step 944, locker controller 715 generates a report message, and sendsthe report message to locker manager 713. The report message may includeinformation indicating that that the package was delivered and depositedin locker compartment 716, or that the locker is empty, or that someobject, other than the package, was deposited in the digital locker.

In step 946, locker manager 713 receives the report message from lockercontroller 715, and uses the content of the report message to generate adelivery report, which is then sent to intermediary 714.

In step 948, intermediary 714 receives the delivery report from lockermanager 713, and forwards the delivery message to seller 718. Thedelivery report may include information indicating that that the packagewas delivered and deposited in locker compartment 716, identificationinformation of the digital locker that contains locker compartment 716,identification of the package, identification of a recipient of thepackage, and the like.

Upon receiving the delivery report, seller 718 becomes aware of the factthat the package whether the package was successfully delivered tolocker compartment 716, or whether the package was not delivered tolocker compartment 716.

7.0 Weight-Based-Verification of Package Retrieval

In an embodiment, a measurement system implemented in a digital lockeris used to determine whether a package was retrieved from a lockercompartment. For example, if a weight reading, determined by a lockersensor of the digital locker, changes from a non-zero value to aboutzero (within a certain tolerance), then the digital locker may determinethat an item deposited in the locker compartment has been removed (orretrieved) from the compartment. Examples of weight-based0verificationof package retrieval are described in FIG. 13

8.0 Weight-Based-Management of a Locker Usage

Weight readings may also be used to determine the time period duringwhich a package remains in a locker compartment, and/or to determinewhether the package remains in a locker compartment longer than it isexpected. For example, if a weight of an item deposited in a lockercompartment remains above a certain weight threshold for several days,and does not change within the several days by more than 10% of theinitial weight of the package, then a digital locker delivery system maygenerate a message indicating that the package has not been timelyretrieved from the compartment. The message may be used as a reminder tourge a recipient of the package to retrieve the package from the locker.

Furthermore, if a package remains in a locker compartment for less thana certain time period, then a sender and/or a recipient of the packagemay be awarded for using the compartment for a short period of time, andthus increasing the efficiency of the digital locker delivery system.The award may include sweepstakes, coupons, merchandise discounts,service discounts, and the like. However, if a package remains in thecompartment longer than a certain time period, then the digital lockerdeliver system may determine disincentives for the sender and/or therecipient of the package for using the compartment for a long period oftime, and thus decreasing efficiency of the digital locker deliverysystem. Examples of such disincentives may include increasing the costof renting digital lockers, limiting a pool of locker compartmentsavailable to a sender, and the like.

9.0 Retrieving Package from a Digital Locker

In an embodiment, a digital locker sends to a sender or a seller of thepackage a delivery report. The report may identify a locker compartmentin which the package has been deposited. For example, the report mayindicate a locker compartment identifier, a location and an access code.Upon receiving the report, the sender (seller) may send a message to arecipient of the package to inform him that the package has beendelivered to the digital locker. In the message, the seller may identifythe location of the digital locker, the access code for the digitallocker, and instructions for picking up the package.

Alternatively, the sender (seller) may send a message to anintermediary, and ask the intermediary to notify the recipient of thepackage that the package is ready to be picked up from the digitallocker. Upon receiving the message, the intermediary may contact therecipient (buyer) and provide the locker compartmentidentifier/location/access code to the recipient (buyer). Alternatively,the sender (seller) himself may contact the recipient (buyer) andprovide the locker compartment identifier/location/access code.

9.1 Flow Chart

FIG. 12 is a flow diagram that depicts an approach for retrieving apackage from a digital locker. The depicted example illustratesinteractions between a seller 1102 and a buyer 1255. For the purpose ofexplaining the example depicted in FIG. 12, it is assumed that thepackage has been already stored in a digital locker, and the informationabout the digital locker and the access code to access the digitallocker have been provided to seller 1102.

In step 1212, seller 1102 sends information about the package to buyer1255. The information may be encoded in a bar code, and the informationmay be emailed, texted or otherwise provided to buyer 1255. Theinformation may include the location information of the digital lockerin which the package was deposited. For example, the locationinformation may indicate the address of a digital locker facility andthe identifier of the digital locker in the facility.

In an embodiment, the information sent in step 1212 does not contain anaccess code to access the digital locker in which the package has beendeposited. In such a situation, the access code is sent to buyer 1255separately from the information identifying the location of the digitallocker.

In step 1214, seller 1102 sends an access code for the digital locker tobuyer 1255. The access code may be used by buyer 1255 to open up thedigital locker to retrieve the package from the locker. The access codemay be pin number, and alpha-numerical string, or other data that buyer1255 may use to open up the digital locker.

In step 1222, buyer 1255 uses the location information of the digitallocker to locate the digital locker, and uses the access code for thedigital locker to open up the locker. The access code may be entered tothe digital locker using a touch panel described in FIG. 3-4. The accesscode may also be entered to the digital locker using any other userinterface provided by the digital locker.

If the access code was entered incorrectly to the digital locker, or ifthe access code was incorrect, then the digital locker will not open thedoor, and buyer 1255 will not be able to retrieve the package. Inaddition, the digital locker may display an error message on a touchscreen indicating the reason for the access failure. Furthermore, thedigital locker may generate and send a message to seller 1102 and/or anintermediary indicating that someone was trying to open up the digitallocker, but the attempt was unsuccessful.

However, if the access code is correct and it was correctly entered tothe digital locker, then the digital locker will open up the door andbuyer 1255 may retrieve the package from a compartment of the digitallocker.

In step 1224, buyer 1255 retrieves the package from a compartment of thedigital locker. Once buyer 1255 retrieves the package, a sensor of thedigital locker may detect that the weight of the compartment (or thecontent in the compartment) has changed, and report the weight change toa locker controller of the digital locker. Then, the locker controllermay report the weight change to a locker manager, as it is described inFIG. 11.

In step 1226, buyer 1255 closes the door of the digital locker. Oncebuyer 1255 closes the door of the locker, a locker sensor of the digitallocker detects that the door has been closed, and report the closing ofthe door to a locker controller, as it is described in FIG. 11.

9.2 Time Chart

FIG. 13 is a time-chart that depicts an approach for retrieving apackage from a digital locker. In the depicted time chart, thecommunications are exchanged between a buyer 720, a bar/QR code reader712, a touch panel 1312, a locker manager 713, an intermediary 714, alocker controller 715, a locker compartment 716, a locker sensor 717,and a seller 718.

The example depicted in FIG. 13 is one of many examples of thecommunications exchanged between entities and elements 710-720 as apackage is retrieved from a digital locker. In other examples, thecommunications may be exchanged between some of the entities andelements 710-720, but not all of them. In yet other examples,communications other than those depicted in FIG. 13 may be exchangedbetween the entities and elements 710-720.

In the example, depicted in FIG. 13, it is assumed that a buyer 720received information about the package. For example, buyer 720 mayreceive the information about the location of the package, an identifierof the digital locker in which the package was deposited, andinstructions regarding retrieving the package from the digital locker.The information may be provided to buyer 720 via email, a text, or anyother form. For example, buyer may receive a text message containing abar code having the information encoded in the bar code.

In step 1320, buyer 720 places the bar code in front of a code readerinstalled in a digital locker. For example, buyer 720 may place the barcode in front of an optical scanner, a bar code reader, or a QR codereader, such as those described in FIG. 3-4.

In step 1322, bar/QR code reader 712 scans the bar code, decodes the barcode, and sends the decoded data to locker manager 713. The decoded datamay include instructions for retrieving the package from the digitallocker. For example, the instructions may indicate an identifier of thedigital locker in which the package is deposited.

In step 1323, locker manager 713 uses the decoded data to obtainadditional information about retrieving of the package. This step isoptional. For example, in some situations, locker manager 713 may verifywhether buyer 720 is authorized to access the digital locker, and/orwhether buyer 720 is authorized to retrieve the package from the digitallocker. Furthermore, locker manager 713 may determine the time at whichbuyer 720 arrived at the digital locker, and communicate the timereading to seller 718 or other entity. The time reading may be used todetermine the time period during which the package remained in acompartment of the digital locker.

In step 1324, locker manager 713 displays instructions on touch panel1312 of the digital locker. The instructions may include the identifierof the digital locker in which the package has been deposited, and howbuyer 720 may retrieve the package.

An access code may be provided to a user using a variety of ways. In anembodiment, the instructions may provide an access code for the digitallocker. The access code may be a pin, or any other code that buyer 720may use open the digital locker.

In an embodiment, buyer 720 receives an access code in a separatecommunication from seller 718 and/or intermediary 714. For example, theaccess code may be provided to buyer 720 as a QR code and may be sent tobuyer 720 as a text.

In step 1326, buyer 720 inputs the access code to touch panel 1312 ofthe digital locker. For example, buyer 720 may use touch panel 1312 tokey-in the access pin to the digital locker. Alternatively, buyer 720may display the access code in front of bar/QR reader 712, and bar/QRcode reader 712 may provide the decoded pin to locker manager 713.

In step 1328, touch panel 1312 sends the access pin for opening thedigital locker to locker manager 713.

In step 1330, locker manager 713 receives the access pin, and determineswhether the access pin is valid. For example, locker manager 713 maycheck whether the received access pin corresponds to any digital lockerthat locker manager 713 manages.

In some situations, the received access pin may not be associated withany digital locker that locker manager 713 manages. For example, buyer720 may have received a valid pin number; however, buyer 720 did notenter the pin number correctly to the digital locker. Also, it mayhappen that buyer 720 did receive an incorrect pin number, and thus thepin number entered to the digital locker may not cause the door of thelocker to open.

Also in step 1330, locker manager 713 may send the received access pinto intermediary 714 with a request to verify whether the pin is correctand/or whether buyer 720 is authorized to use the received access pin.

In step 1332, intermediary 714 receives a request to verify the accesspin. Intermediary 714 may try to verify the access pin by checkingwhether intermediary 714 has any record of distributing the access pinto buyer 720. Alternatively, intermediary 714 may send a request toverify the access pin to seller 718.

Assuming that the access pin is valid and can be used to open thedigital locker, in step 1334, locker manager 713 sends a signal tolocker controller 715 to open the door of the digital locker.

In step 1336, locker controller receives the signal to open the door ofthe digital locker, and causes the opening of the door of the locker.

In step 1338, buyer 720 retrieves the package from the digital locker.Once the package is retrieved from the locker, locker sensor 717, instep 1340, detects that the weight of the locker compartment haschanged, and obtains a reading of the weight of the compartment. Then,locker sensor 717 sends the weight reading to locker controller 715.

Upon receiving the weight reading from locker sensor 717, lockercontroller 715 may determine whether the weight reading indeed indicatesa zero weight (within a certain tolerance). If so, then lockercontroller 715 may generate a message and send the message to seller 718to inform seller 718 that the package was retrieved from the digitallocker.

In step 1342, buyer 720 closes the door of the digital locker.

In step 1344, locker sensor 717 detects that the door of the compartmentof the digital locker has been closed, and reports the closing of thedoor to locker controller 715.

In step 1346, locker controller 715 receives the indication from lockersensor 717 that the door of the locker compartment 716 has been closed,and causes locking of the locker compartment. Various ways of initiatingthe locking of the locker compartment are described in FIG. 6.

In step 1348, locker controller 715 reports a pickup of the package fromthe digital locker to locker manager 713. For example, locker controller715 may send a message to locker manager 713 indicating an identifier ofthe digital locker, the timestamp of the time at which the package wasretrieved from the digital locker, and other information.

In step 1350, locker manager 713 reports picking up of the package fromthe digital locker to intermediary 714. For example, locker manager 713may send a message to intermediary 714 indicating an identifier of thedigital locker, the timestamp of the time at which the package wasretrieved from the digital locker, and other information.

In step 1352, intermediary 714 reports picking up of the package fromthe digital locker to seller 718. For example, intermediary 714 may senda message to seller 718 indicating an identifier of the digital locker,the timestamp of the time at which the package was retrieved from thedigital locker, and other information.

In an embodiment, seller 718 may be informed of various steps performedby buyer 720 as the buyer retrieves the package from the digital locker.For example, seller 718 may receive a request to verify an access pinthat buyer 720 tries to use to open a locker compartment of the digitallocker to retrieve the package from the compartment. The request may besent from an intermediary 714, as it is depicted in FIG. 13, or fromother entity. For example. Seller 718 may receive the request to verifythe access pin from locker manager 713 if the locker manager canretrieve the contact information to seller 718.

Seller 718 may also receive indications that a locker compartment becameempty. For example, seller 718 may receive a message from intermediary714 or locker manager 713 if they were informed that the weight of thelocker compartment changed from a non-zero weight to a zero weight.

Seller 718 may also receive a report that the package was picked up fromthe digital locker. The report may be received from intermediary 714,and may indicate to seller 718 that the package was indeed retrievedfrom the locker compartment, and may indicate the time at which thepacket was retrieved from the compartment. For example, seller 718 mayreceive the report containing an identification of the digital locker,and a timestamp indicating the time at which buyer 720 picked up thepackage.

Although an access pin number has been described here as a medium forenabling access to the digital locker, alternative systems may use othermethods of facilitating access to the locker. For example, buyer 720 maybe identified using a face recognition system or a finger papillarylines recognition application, and access to the digital locker may befacilitated using a mobile phone. For instance, buyer 720 may launch amobile application on his mobile phone, and use the Bluetooth wirelesstechnology and the mobile application to send data to the digital lockerand to receive data from the digital locker.

In an embodiment, the approach selects the best-fit digital locker forstoring a package. The best-fit locker may be selected as the lockerthat is large enough to hold the package, but if several lockers arelarge enough to hold the package, then the smallest of them may beselected as the best-fit digital locker.

Finding the best-fit locker for a package may be implemented by using avariety of sensors, including optical sensors, mechanical sensors,infra-red sensors, and the like. The sensors may determine themeasurements of the package, as well as the weight of the package. Usingthe best-fit-locker approach may improve the utilization of the digitallockers and improve the management of the lockers.

In an embodiment, the approach uses sensors to detect whether a packagewas delivered to a digital locker, whether a package was retrieved froma digital locker, how long the package remained in a digital lockerbefore the package was retrieved from the locker, and the like. Thesensors may be configured to determine various characteristics of theobjects placed in the digital locker, including the weight andmeasurements of the objects. Reports generated by locker sensors mayinclude readings of the weight and measurements of the object stored inthe locker.

Using the weight measurements to determine whether a package isdelivered or retrieved from a digital locker is a more accurate approachthan the approach based on for example, just optical sensors because theoptical sensors are sensitive to dust and other particles obscuring thelight. For example, if some dust particles obscure the light measured byan optical sensor in a digital locker, then the optical sensor mayobtain a reading indicating that some object is present in the digitallocker even if the locker is empty.

In contrast, a weight-sensor may provide readings of the weight of thecontent of the locker that indicate the presence or the absence of anobject in the digital locker with a better accuracy than an opticallocker can provide.

For example, FIG. 5 is a block diagram that illustrates a computersystem 500 upon which an embodiment of the disclosure may beimplemented. Computer system 500 includes a bus 502 or othercommunication mechanism for communicating information, and a hardwareprocessor 504 coupled with bus 502 for processing information. Hardwareprocessor 504 may be, for example, a general purpose microprocessor.

Computer system 500 also includes a main memory 506, such as a randomaccess memory (RAM) or other dynamic storage device, coupled to bus 502for storing information and instructions to be executed by processor504. Main memory 506 also may be used for storing temporary variables orother intermediate information during execution of instructions to beexecuted by processor 504. Such instructions, when stored innon-transitory storage media accessible to processor 504, rendercomputer system 500 into a special-purpose machine that is customized toperform the operations specified in the instructions.

Computer system 500 further includes a read only memory (ROM) 508 orother static storage device coupled to bus 502 for storing staticinformation and instructions for processor 504. A storage device 510,such as a magnetic disk or optical disk, is provided and coupled to bus502 for storing information and instructions.

Computer system 500 may be coupled via bus 502 to a display 512, such asa cathode ray tube (CRT), for displaying information to a computer user.An input device 514, including alphanumeric and other keys, is coupledto bus 502 for communicating information and command selections toprocessor 504. Another type of user input device is cursor control 516,such as a mouse, a trackball, or cursor direction keys for communicatingdirection information and command selections to processor 504 and forcontrolling cursor movement on display 512. This input device typicallyhas two degrees of freedom in two axes, a first axis (e.g., x) and asecond axis (e.g., y), that allows the device to specify positions in aplane.

Computer system 500 may implement the techniques described herein usingcustomized hard-wired logic, one or more ASICs or FPGAs, firmware and/orprogram logic which in combination with the computer system causes orprograms computer system 500 to be a special-purpose machine. Accordingto one embodiment, the techniques herein are performed by computersystem 500 in response to processor 504 executing one or more sequencesof one or more instructions contained in main memory 506. Suchinstructions may be read into main memory 506 from another storagemedium, such as storage device 510. Execution of the sequences ofinstructions contained in main memory 506 causes processor 504 toperform the process steps described herein. In alternative embodiments,hard-wired circuitry may be used in place of or in combination withsoftware instructions.

The term “storage media” as used herein refers to any non-transitorymedia that store data and/or instructions that cause a machine tooperation in a specific fashion. Such storage media may comprisenon-volatile media and/or volatile media. Non-volatile media includes,for example, optical or magnetic disks, such as storage device 510.Volatile media includes dynamic memory, such as main memory 506. Commonforms of storage media include, for example, a floppy disk, a flexibledisk, hard disk, solid state drive, magnetic tape, or any other magneticdata storage medium, a CD-ROM, any other optical data storage medium,any physical medium with patterns of holes, a RAM, a PROM, and EPROM, aFLASH-EPROM, NVRAM, any other memory chip or cartridge.

Storage media is distinct from but may be used in conjunction withtransmission media. Transmission media participates in transferringinformation between storage media. For example, transmission mediaincludes coaxial cables, copper wire and fiber optics, including thewires that comprise bus 502. Transmission media can also take the formof acoustic or light waves, such as those generated during radio-waveand infra-red data communications.

Various forms of media may be involved in carrying one or more sequencesof one or more instructions to processor 504 for execution. For example,the instructions may initially be carried on a magnetic disk or solidstate drive of a remote computer. The remote computer can load theinstructions into its dynamic memory and send the instructions over atelephone line using a modem. A modem local to computer system 500 canreceive the data on the telephone line and use an infra-red transmitterto convert the data to an infra-red signal. An infra-red detector canreceive the data carried in the infra-red signal and appropriatecircuitry can place the data on bus 502. Bus 502 carries the data tomain memory 506, from which processor 504 retrieves and executes theinstructions. The instructions received by main memory 506 mayoptionally be stored on storage device 510 either before or afterexecution by processor 504.

Computer system 500 also includes a communication interface 518 coupledto bus 502. Communication interface 518 provides a two-way datacommunication coupling to a network link 520 that is connected to alocal network 522. For example, communication interface 518 may be anintegrated services digital network (ISDN) card, cable modem, satellitemodem, or a modem to provide a data communication connection to acorresponding type of telephone line. As another example, communicationinterface 518 may be a local area network (LAN) card to provide a datacommunication connection to a compatible LAN. Wireless links may also beimplemented. In any such implementation, communication interface 518sends and receives electrical, electromagnetic or optical signals thatcarry digital data streams representing various types of information.

Network link 520 typically provides data communication through one ormore networks to other data devices. For example, network link 520 mayprovide a connection through local network 522 to a host computer 524 orto data equipment operated by an Internet Service Provider (ISP) 526.ISP 526 in turn provides data communication services through the worldwide packet data communication network now commonly referred to as the“Internet” 528. Local network 522 and Internet 528 both use electrical,electromagnetic or optical signals that carry digital data streams. Thesignals through the various networks and the signals on network link 520and through communication interface 518, which carry the digital data toand from computer system 500, are example forms of transmission media.

Computer system 500 can send messages and receive data, includingprogram code, through the network(s), network link 520 and communicationinterface 518. In the Internet example, a server 530 might transmit arequested code for an application program through Internet 528, ISP 526,local network 522 and communication interface 518.

The received code may be executed by processor 504 as it is received,and/or stored in storage device 510, or other non-volatile storage forlater execution.

A method comprising:determining, by a sensor, a weight of an item placed in a lockercompartment; transmitting to a locker controller, data indicating theweight of the item placed in the locker compartment; receiving, from thesensor, the data indicating the weight of the item placed in the lockercompartment; in response to receiving, from the sensor, the dataindicating the weight of the item placed in the locker compartment,transmitting, by the locker controller, the data indicating the weightof the item placed in the locker compartment to a locker manager;receiving, from the locker controller, the data indicating the weight ofthe item placed in the locker compartment; determining a lockeridentifier of the locker compartment in which the item is placed;generating a request for providing a reference weight of the item;wherein the request includes the locker identifier; sending the request,including the locker identifier, to an intermediary device that stores aplurality of associations between a plurality of locker identifiers anda plurality of reference weights of items; in response to receiving,from the intermediary device, a response to the request, retrieving,from the response, the reference weight of the item; verifying theweight of the item placed in the locker compartment based, at least inpart, upon the data indicating the weight of the item placed in thelocker compartment and the reference weight of the item; and generatingand transmitting a report message indicating whether the item has beendelivered to the locker compartment; wherein the method is performedusing one or more computing devices.
 16. The method of claim 15, furthercomprising: extracting a weight value from the data indicating theweight of the item; determining an identification of the item placed inthe locker compartment; requesting the reference weight of the itemidentified by the identification; in response to receiving the referenceweight of the item, comparing the weight value with the referenceweight; in response to determining that the weight value matches thereference weight within an error margin, determining that the item wasdelivered to the locker compartment; and in response to determining thatthe weight value does not match the reference weight within the errormargin, determining that the item deposited in the locker compartment isincorrect.
 17. The method of claim 15, further comprising: detectingwhether a door of the locker compartment has been closed; in response todetecting that the door of the locker compartment has been closed,transmitting, to the locker controller, a notification indicating thatthe door of the locker compartment has been closed; in response toreceiving the notification indicating that the door of the lockercompartment has been closed, transmitting a package delivery report tothe locker manager; in response to receiving the package delivery reportand determining that the weight of the item placed in the lockercompartment matches the reference weight, reporting that the item hasbeen delivered to the locker compartment; and in response to determiningthat the weight of the item does not match the reference weight,reporting that the item has not been delivered to the lockercompartment.
 18. The method of claim 15, further comprising: receivingsensor information from the sensor and, based on the sensor information,determining whether the item has been removed from the lockercompartment; in response to determining that the item has been removedfrom the locker compartment, determining a time period during which theitem remained in the locker compartment; generating a notificationindicating the time period during which the item remained in the lockercompartment; and transmitting the notification to an intermediary;wherein the intermediary, upon receiving the notification, determineswhether the time period exceeds a reference time period.
 19. The methodof claim 15, further comprising: receiving, from the sensor, a weightreading for the locker compartment; comparing the weight reading of theitem placed in the locker compartment with the reference weight for theitem; determining whether the reference weight exceeds the weightreading by a first value; and in response to determining that thereference weight exceeds the weight reading by the first value,determining that that item has been removed from the locker compartment.20. The method of claim 19, further comprising: in response todetermining that the reference weight exceeds the weight reading by thefirst value, determining a time period during which the item remained inthe locker compartment; generating a notification indicating the timeperiod during which the item remained in the locker compartment; andtransmitting the notification to an intermediary; wherein theintermediary, upon receiving the notification, determines whether thetime period exceeds a reference time period, and if so, sends a reminderto a buyer to indicate that the item is ready in the locker compartmentfor a pickup.
